Tolerance Stack-Up Analysis — Why Your Parts Don't Fit：核心...

[henry_huang]

Tolerance stack-up analysis explained:

What: Calculating cumulative effect of individual tolerances on final assembly fit.

Methods:

1. Worst-case (simplest, most conservative)
2. RSS (Root Sum Square, more realistic)
3. Monte Carlo simulation (most accurate)

A good rule: design tolerance 30-50% tighter than required to account for stack-up.
